Metal weather strip



Dec. 31, 1929. A. M. LANE METAL WEATHER STRIP Filed March 2. 1928 Patented Dec. 31, 1929 UNITED STATES PATENT OFFICE ALFRED M. LANE, OF ST. LOUIS, MISSOURI, ASSIGNOR TO GENERAL \VEATHERSTRIP COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF 1VIISSOURI METAL WEATHER STRIP Application filed March 2, 1928.

This invention relates to metal weatherstrips particularly adapted for windows of the sliding sash type. The invention has for its principal objects to provide an efficient Weatherstrip of simple and economical construction which can be readily applied to such windows without alterationv or removal of any of the parts thereof and which will automatically accommodate itself to the shrinking and swelling of the window frame or sash and at the same time maintain a weatherproof joint between the meeting edges of the sash and frame.

The invention consists in the Weatherstrip and in the construction, combinations and arrangements of parts hereinafter described and claimed.

In the accompanying drawing, which forms part of this specification and wherein like symbols refer to like parts wherever they occur.

Fig. 1 is a fragmentary horizontal crosssection through one side of a window frame and the adjacent portion of a sliding sash provided with a metal Weatherstrip embodying my invention; and

Fig. 2 is a fragmentary perspective View, showing a section of the strip detached.

Referring to Fig. 1 of the accompanying drawing, my invention is shown in connection with the casing of jamb member 1 of an ordinary double hung window equipped With a closure member in the form of a sliding sash 2, the respective walls of the vertical slideway or runway for the sash being formed by a parting strip 3 and a stop or moulding 1; but the invention is applicable to doors and other types of windows having swinging closures.

The present Weatherstrip A comprises a strip of spring bronze or other resilient metal of substantially Z-shaped cross-section; that is, said strip comprises an oblique web portion 5 having a lateral flange 6 along one edge disposed on one side of the web and a lateral flange 7 on its opposite edge disposed on the opposite side of said web. As shown in the drawing, the free marginal edges of the lateral flanges 6 and 7 are rebent or hemmed, as at 8, to reinforce and stiffen the Serial No. 258,471.

outer edges of said flanges, and the oblique web portion 5 of said strip is disposed at an obtuse angle to the flange 6. The flange 6 is made flat; and the flange 7 is reversely curved in directions transverse to its length to form two reverse corrugations 9 and 10, respectively, which extend longitudinally of the flange 7 from end to end thereof.

In applying the strip A to the window construction shown in Fig. 1, said strip is positioned in the window with its corrugated marginal flange 7 between the opposing faces of the sash 2 and jamb 1, with its web 5 between the opposing faces of the sash and parting strip 3, and with its fiat flange 6 bearing flatwise against the inner edge of said parting strip and securely fastened thereto along its outer edge preferably by a row of nails 11. Then thus secured in position the corrugation 9 in the marginal flange 7 of the Z-shaped Weatherstrip bears against the amb 1 and the other corrugation 10 bears against the sash 2, thereby sealing the space between the sash and jamb along two lines; and the resilient web 5 of said strip is disposed in the space or joint between the sash and parting bead at an oblique angle and resiliently engages the adjacent vertical corner of the sash and thus closes or seals the space between the sash and parting bead.

By the arrangement described, the corrugated margin of the strip A and the oblique Web thereof are adapted to yield and accommodate themselves to the shrinking and swelling of the sash while maintaining weatherproof joints between the sash and the jamb and the parting bead. Another advantage of the strip is that it takes up any play or looseness between the sash and the jamb and the side of the runway and thus prevents rattling of the sash without interfering with the easy sliding movement thereof. Another advantage of the foregoing construction is that it permits the sash to be removed without disturbing the strip and the strip to be attached to and removed from the window without disturbing the sash.

Obviously, the invention is not limited to use with the window construction shown and described.

What I claim is:

1. The combination of a frame and a closure therefor, of a resilient metal Weatherstrip secured to said frame member adjacent to said closure, said Weatherstrip having an oblique portion ada ted to resiliently engage a corner of said closure and a longitudinally corrugated free marginal portion located between and resiliently engaging the opposing faces of said frame and said closure, respectively, along spaced lines.

2. The combination of a frame and a closure therefor, of a resilient metal Weatherstrip secured to said frame member adjacent to said closure, said Weatherstrip having an oblique portion adapted to resiliently engage a corner of said closure and a reversely corrugated free marginal flange located between the opposing faces of said closure and said frame, one of said corrugations bearing against said frame along one line and the other of said corrugations bearing against said closure along another line offset from said first mentioned line.

3. The combination with a window frame having a vertical slidway and a sash slidably mounted in said slideway, of a metal Weatherstrip for said slideway, said strip comprising a strip of metal of substantially Z-shaped section arranged with its web between one side of a slideway and the adjacent side face of the sash, one flange of said strip being secured to the window frame along the edge of said slideway and the other flange being longitudinally corrugated and extending into the space between the edges of said sash and the bottom of said slideway.

4. The combination with a window frame having a vertical slideway and a sash slidably mounted in said slideway, of a metal Weatherstrip for said slideway, said strip comprising a strip of metal of substantially Z-shaped section arranged with its web between one side of a slideway and the adjacent side face of the sash, one flange of said strip being secured to the window frame along the edge of said slideway and the other flange being longitudinall corrugated and extending into the space between the edge of said sash and the bottom of said slideway, said web resiliently engaging the corner of said sash and the corrugations bearing against the edge of the sash and the bottom of the slideway.

5. The combination of a window frame having a vertical slideway, the respective walls of which are formed by a parting strip and a stop, and a sash slidably mounted in said slideway of a Weatherstrip comprising a web portion disposed between the parting strip and the sash and adapted to bear against the latter, a marginal flange secured to said parting bead and a free marginal flange extending between the edge of the sash and the slideway, said free marginal flange being reversely curved in directions transverse to its length to form two reverse corrugations, one of said corrugations hearing against the bottom of said slideway along one line and the other corrugation bearing against the opposing face of said sash along aline oflset with respect to said first mentioned line.

6. A resilient metal weatherstri comprising a web portion having a lateral ange along one edge disposed on one side of the web and a lateral flange on its opposite edge disposed on the opposite side of the web, one of said flanges being flat and the other of said flanges being reversely curved in directions transverse to its length to form reverse corrugations.

7 A resilient metal Weatherstrip comprising an oblique web portion having a lateral flange along one edge disposed on one side of the web and a lateral flange on its opposite edge disposed on the opposite side of the web, one of said flanges being longitudinally corrugated.

8. A resilient metal Weatherstrip comprising an oblique web portion having a lateral flange along one edge disposed on one side of the web and a. lateral flange on its opposite edge disposed on the opposite side of the web, one of said flanges being flat and the other said flanges being longitudinally corrugated, the oblique web portion of the strip being disposed at obtuse angle to the flat marginal flange thereof.
